Product Overview
A round taper rubber cable grommet provides a shaped transition at a circular cable opening. Its tapered form makes orientation and seating depth important parts of the fit. Custom molding can adapt the profile to the panel and cable, including the retaining area and the passage through the center.
The taper should guide the part into its intended position without leaving the cable opening stretched out of shape. Compare the receiving hole with the part at the actual seating location, rather than using the widest outer dimension alone. The wall thickness and the space behind the panel also determine whether the profile can sit correctly.
For dust control, the panel contact and cable contact both need attention. An insert that fits the panel well may still leave a gap around a smaller cable. Keep the mating surfaces clean during assembly and check that the cable does not tilt the grommet after routing. Any required enclosure protection should be evaluated with the complete entry assembled and the cable in its normal working position.
- Material options
- Custom rubber compound and color, selected for the contact conditions and required geometry.
- Hardness range
- 30–90 Shore A for rubber. Assess the grade against this fit requirement: Compare the receiving hole with the part at the actual seating location, rather than using the widest outer dimension alone.
- Custom profile & fit
- The taper should guide the part into its intended position without leaving the cable opening stretched out of shape.
- Assembly considerations
- Any required enclosure protection should be evaluated with the complete entry assembled and the cable in its normal working position.
- Design check
- Keep the mating surfaces clean during assembly and check that the cable does not tilt the grommet after routing.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
